To review, a metaphor is comparing two unlike things wherein one thing is said to be the other. Examples of metaphor in this poem include:

Imagery is the use of language to create strong visual connections about which the author is writing in the readers mind. Examples of imagery include:

My penmanshipsharpens up. I go to school.Slowly the words appearon a line.

Personification is to give human characteristics to non-human things. The following is an example of this:

The second l in reallystaggered into a ythe letters gotdrunk.

The connotation (what is implied here) is that there are so many things of common nature between the two lands, the two cultures, the two citizens that it seems ridiculous that there is so much enmity in the mind of the speaker (who probably speaks for a lot of citizens)
